The Gateway Clipper Fleet, founded by John E. Connelly, is a Pittsburgh, Pennsylvania-based fleet of riverboats. The fleet cruises the three rivers of Pittsburgh - the Monongahela, Allegheny, and Ohio. The fleet is named after the city of Pittsburgh, which in earlier times was known as the "Gateway to the West". The original riverboat was Gateway Clipper, which set sail in 1958. By the mid-1960s, the fleet was composed of three craft, Gateway Clipper, Party Liner, and Good Ship Lollipop. In 1999 it added its fifth ship. In 2008 the Gateway Clipper Fleet celebrated its 50th year of sailing on the Three Rivers. In 2013, the fleet added its sixth ship, the all-steel classic paddle wheel Three Rivers Queen.
